No question G2 is great. My question is about the add ons. I have #1 so I could fly the Big Stick. I'm tempted to pick up 2,3,4, but I'm wondering if they are worth it. I'm not interested in the battleship or other silly things that are not realistic. I want to fly planes modeled as good as the Big Stick. I want "Real", not just fun. To me G2 is a tool not a toy. With that in mind, would you all recommend vol. 2 and/or 3 and/or 4.

Thanks guys,
Please advise.
